Impact of Water on Offshore Structures and Infrastructure

Abstract

A characteristic phenomenon in offshore engineering is the impact of water on individual devices and elements of dynamic systems. This impact is a very complex phenomenon composed, among other things, of wave action, sea currents, hydrostatic and hydrodynamic forces. These processes are difficult to describe, and there exists a handful of approaches to modelling them, which differ in the level of idealization [Newman J. N., 1977], [Mei C. C., 1989], [Faltinsen O. M., 1990]. A possibly simple description of the motion of an offshore structure’s base is often desirable, e.g. in the problems of control [Fossen T. I., 1994].
